Top 10 Foods Highest in Copper

Copper is an essential mineral required by the body for bone and connective tissue production, and for coding specific enzymes that range in function from eliminating free radicals to producing melanin. A deficiency in copper can lead to osteoporosis, joint pain, lowered immunity, and since copper is essential for the absorption of iron, anemia. Conversely, over-consumption of copper will lead to cramps, diarrhea, and vomiting in the short term, and can lead to depression, schizophrenia, hypertension, senility, and insomnia in the long term. Copper in large amounts can even be poisonous.

High copper foods include seafood, kale, mushrooms, seeds, nuts, beans, dried fruit, avocados, goat cheese, and fermented soy foods. The stomach needs to be acidic in order to absorb copper and thus antacids interfere with the absorption of copper, as do milk and egg proteins. The current DV for copper is 2mg. Below is a list of high copper foods, for more, see the lists of high copper foods by nutrient density, and copper rich foods.
